'GEORGE BENDER AND BENJAMIN F. CONNEB, OF NEW YORK, N. Y., ASSIGrNORS TOBENTLEY, CONNER & 00., OF SAME PLACE.

LEAD OR RULE CUTTER.

SPECIFICATION forming part of Letters Patent No. 532,521, dated January15, 1895. 1

Application filed October 18, 1894. Serial No. 526,265. (No model.)

.rules to desired lengths, and has as its object certain improvementswhereby the movable blade of the cutter can be readily adjusted atdifferent angles so as to give a horizontal cut or a shear out, wherebyeither leads or brass rules may be cut with the same cutterblades.

Ourimprovements also relate to an adj ustable gage and to other detailshereinafter described.

In the drawings, Figure l, is a right end view of the cutter. Fig. 2, isa view of the opposite end. Fig. 3, is a front elevation, and Fig. 4: isaplan view,with the upper portion of the cutter broken away.

Similar letters designate similar parts in all the drawings.

The base or frame of the cutter consists of the casting A, to which isattached the stationary center blade B. The arm 0 is pivoted to theframe A by the bolt D, and is provided with an extended portion E whichfits evenly against the side of the frame A, and by its extended bearingprevents lateral vibration in the arm 0 when in operation. The lever Cis pivoted to the standard A of the base A, and is connected to the arm0 by link 0 Ontthe side of the arm 0, next to the sta tionary blade B,is a rabbet to accommodate the movable blade F, which is 'pivoted to thearm 0 by the pivot f. A set screw 9 passes through a slot 0 in the arm0, and engages with the blade F. A rod h isjournaled in the arm 0 and isprovided at its inner end witha cam 'i, the upper side of whichbearsagainst the upper edge of the rabbet, while the lower side thereofengages the upper edge of the blade F. By. loosening the set screw 9,the blade F is left free upon its pivot f. The cam 'iis then turned soasto interpose its longer or shorter diameter between the blade F andthe arm 0. The blade is then brought firmly against the cam, and securedin place by the set screw g. By thismeans any desired angle can be givento the blade F, and a firm backing is provided for it by means of thecam 2 G is a graduated gage, which slides in the guides H, H and isprovided at its end with the stop I.

J is a' locking cam which fits into the recesses j jj, which are placedat pica distances on the lower side of the gage G. The for ward edge ofthe cam J is beveled to correspond with the inclined forward sides ofthe recessesjj j, so that when the gage is slid approximately to thedesired position, the cam J is turned into position and by the pressureof its beveled edge against the inclined side of the groove forces thegage forward until the vertical rear side of the recess comes in contactwith the rear side of the cam, when the gage will be locked at a truepica distance.

If an odd length is to be cut, the distance is measured between theguide H and the stop K on the gage G, which is then secured by the setscrew L.

M is an extended arm which is adapted to support the forward end of thegage G and alsoserves to sustain the lead or rule as it is fed forwardto the stop I. This prevents the lead from bending or sagging orspringing so as to give an uneven measure when out. By this means wesecure a lead and rule outter with a single bed N to support the metalwhile being cut, and-with a single movable cutting blade which can bereadily adjusted at different angles to the stationary cutting blade,and when adjusted shall be firm and durable. We also secure a greatlyimproved gage, and an automatic justifying lock for the same, and weprovide a supportboth for the extended end of the gage and for theprojecting end of the lead or rule.

Having thus described our invention, what we claim, and desire to secureby Letters Patent of the United States, is

1. In alead and rule cutter the combination with a bed provided with astationary cutter blade, of an oscillating arm, with an extended rearend, pivoted to said bed, provided with a 'rabbeted recess therein, amovable cutter-blad e, adjusted in said recess, piv- ICO oted at oneend, supported at its other end by an eccentric cam interposed betweenthe cutter-blade and the arm, and secured in place by a set screw,substantially as and for the purposes set forth.

2. In a lead and rule cutter an adjustable gage G provided at picadistances with recesses having inclined forward edges and vertical rearedges,a locking cam provided with a similarly inclined forward edge anda vertical rear edge, adapted to adjust the gage to true pica measuresby locking into said recesses, substantially as and for the purposes setforth.

The combination in a lead and rule outter of an adjustable graduatedgage, provided with a stop at its forward end to arrest the lead orrule, a measuring stop attached to said gage at the same distance fromthe rear guide as the front stop is from the cutting blades; recesses atpica distances upon said gage provided with inclined forward sides andvertical rear sides, a locking cam with inclinedforward edge andvertical rear edge adapted to look into said recesses; guides for saidgage to slide in, and a set screw in one of said guides to secure thegage, substantially as and for the purposes set forth.

4. In a lead and rule cutter, the combination of the base or frame A,stationary blade B, the rabbeted arm 0 pivoted thereto, provided with arear extension E, cutter blade F, pivot f, set screw g, rod h, cam i,graduated gage G, provided with the stops I and K, and recesses j j j,locking cam J, set screw L, guides H, H, and arm M, substantially as andfor the purposes set forth.
